, let me come over to you, a lot of talkaboutmiranda. butgive me a sense of what the leeway is especially in situations like this, after acts like what happened here at the marathon. >> well, it is yesterday's news. he's been given his miranda warnings and probably anything he said without his miranda warnings is not going to be needed by the government or the prosecution. remember, they did not indict him as a terrorist, that's very important. they indicted him as an ordinary murderer, anybody who wants to kill their mother-in-law, business partner and makes an improvised explosive device and kills them is just as guilty under the statute indicted as osama bin laden might be. this is not a terrorist prosecution. they don't have to prove intent to terrorize, intent to intimidate. they can prove their case just through the videotapes. now, i predict there are going to be two types of possible defenses in this case. number one, the jihad defense. i did it, i'm proud, i'm happy, please kill me, i want to join my brother in paradise. i'm a martyr. the other, my brother made me d
